d2030aaa50 clk: qcom: ipq5018: keep XO clock always on
[ Upstream commit 693a723291 ]

The XO clock must not be disabled to avoid the kernel trying to disable
the it. As such, keep the XO clock always on by flagging it as critical.

[ Upstream commit 0429415a08 ]

Prevent the PWM value from being set to minimum when thermal zone
temperature exceeds any trip point during driver probe. Otherwise, the
PWM fan speed will remains at minimum speed and not respond to

d006f8cbec watchdog: dw_wdt: Fix default timeout
[ Upstream commit ac3dbb91e0 ]

The Synopsys Watchdog driver sets the default timeout to 30 seconds,
but on some devices this is not a valid timeout. E.g. on RK3588 the
actual timeout being used is 44 seconds instead.

Once the watchdog is started the value is updated accordingly, but
it would be better to expose a sensible timeout to userspace without
the need to first start the watchdog.

62b4f6c6ab fs/orangefs: use snprintf() instead of sprintf()
[ Upstream commit cdfa130465 ]

sprintf() is discouraged for use with bounded destination buffers
as it does not prevent buffer overflows when the formatted output
exceeds the destination buffer size. snprintf() is a safer
alternative as it limits the number of bytes written and ensures
NUL-termination.

Replace sprintf() with snprintf() for copying the debug string
into a temporary buffer, using ORANGEFS_MAX_DEBUG_STRING_LEN as
the maximum size to ensure safe formatting and prevent memory
corruption in edge cases.

EDIT: After this patch sat on linux-next for a few days, Dan
Carpenter saw it and suggested that I use scnprintf instead of
snprintf. I made the change and retested.

35782c3252 scsi: libiscsi: Initialize iscsi_conn->dd_data only if memory is allocated
[ Upstream commit 3ea3a256ed ]

In case of an ib_fast_reg_mr allocation failure during iSER setup, the
machine hits a panic because iscsi_conn->dd_data is initialized
unconditionally, even when no memory is allocated (dd_size == 0).  This
leads invalid pointer dereference during connection teardown.

Fix by setting iscsi_conn->dd_data only if memory is actually allocated.

37ed0eeadb mfd: axp20x: Set explicit ID for AXP313 regulator
[ Upstream commit 88828c7e94 ]

On newer boards featuring the A523 SoC, the AXP323 (related to the
AXP313) is paired with the AXP717 and serves as a secondary PMIC
providing additional regulator outputs. However the MFD cells are all
registered with PLATFORM_DEVID_NONE, which causes the regulator cells
to conflict with each other.

Commit e37ec32188 ("mfd: axp20x: Allow multiple regulators") attempted
to fix this by switching to PLATFORM_DEVID_AUTO so that the device names
would all be different, however that broke IIO channel mapping, which is
also tied to the device names. As a result the change was later reverted.

Instead, here we attempt to make sure the AXP313/AXP323 regulator cell
does not conflict by explicitly giving it an ID number. This was
previously done for the AXP809+AXP806 pair used with the A80 SoC.

ec12068f10 cifs: Fix calling CIFSFindFirst() for root path without msearch
[ Upstream commit b460249b9a ]

To query root path (without msearch wildcard) it is needed to
send pattern '\' instead of '' (empty string).

This allows to use CIFSFindFirst() to query information about root path
which is being used in followup changes.

This change fixes the stat() syscall called on the root path on the mount.
It is because stat() syscall uses the cifs_query_path_info() function and
it can fallback to the CIFSFindFirst() usage with msearch=false.

680c7d9d91 vsock/virtio: Resize receive buffers so that each SKB fits in a 4K page
[ Upstream commit 03a92f036a ]

When allocating receive buffers for the vsock virtio RX virtqueue, an
SKB is allocated with a 4140 data payload (the 44-byte packet header +
VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE). Even when factoring in the SKB
overhead, the resulting 8KiB allocation thanks to the rounding in
kmalloc_reserve() is wasteful (~3700 unusable bytes) and results in a
higher-order page allocation on systems with 4KiB pages just for the
sake of a few hundred bytes of packet data.

Limit the vsock virtio RX buffers to 4KiB per SKB, resulting in much
better memory utilisation and removing the need to allocate higher-order
pages entirely.

1cfa244f71 rcu: Fix rcu_read_unlock() deadloop due to IRQ work
[ Upstream commit b41642c877 ]

During rcu_read_unlock_special(), if this happens during irq_exit(), we
can lockup if an IPI is issued. This is because the IPI itself triggers
the irq_exit() path causing a recursive lock up.

This is precisely what Xiongfeng found when invoking a BPF program on
the trace_tick_stop() tracepoint As shown in the trace below. Fix by
managing the irq_work state correctly.

irq_exit()
  __irq_exit_rcu()
    /* in_hardirq() returns false after this */
    preempt_count_sub(HARDIRQ_OFFSET)
    tick_irq_exit()
      tick_nohz_irq_exit()
	    tick_nohz_stop_sched_tick()
	      trace_tick_stop()  /* a bpf prog is hooked on this trace point */
		   __bpf_trace_tick_stop()
		      bpf_trace_run2()
			    rcu_read_unlock_special()
                              /* will send a IPI to itself */
			      irq_work_queue_on(&rdp->defer_qs_iw, rdp->cpu);

A simple reproducer can also be obtained by doing the following in
tick_irq_exit(). It will hang on boot without the patch:

  static inline void tick_irq_exit(void)
  {
 +	rcu_read_lock();
 +	WRITE_ONCE(current->rcu_read_unlock_special.b.need_qs, true);

f6eaa8ba86 drm/ttm: Respect the shrinker core free target
[ Upstream commit eac21f8ebe ]

Currently the TTM shrinker aborts shrinking as soon as it frees pages from
any of the page order pools and by doing so it can fail to respect the
freeing target which was configured by the shrinker core.

We use the wording "can fail" because the number of freed pages will
depend on the presence of pages in the pools and the order of the pools on
the LRU list. For example if there are no free pages in the high order
pools the shrinker core may require multiple passes over the TTM shrinker
before it will free the default target of 128 pages (assuming there are
free pages in the low order pools). This inefficiency can be compounded by
the pool LRU where multiple further calls into the TTM shrinker are
required to end up looking at the pool with pages.

Improve this by never freeing less than the shrinker core has requested.

At the same time we start reporting the number of scanned pages (freed in
this case), which prevents the core shrinker from giving up on the TTM
shrinker too soon and moving on.

v2:
 * Simplify loop logic. (Christian)
 * Improve commit message.

verifier explores the branches under rX == 0 in check_cond_jmp_op()
even if reg->type is CONST_PTR_TO_MAP, because it was not checked for
in reg_not_null().

Fix this by adding CONST_PTR_TO_MAP to the set of types that are
considered non nullable in reg_not_null().

An old "unpriv: cmp map pointer with zero" selftest fails with this
change, because now early out correctly triggers in
check_cond_jmp_op(), making the verification to pass.

In practice verifier may allow pointer to null comparison in unpriv,
since in many cases the relevant branch and comparison op are removed
as dead code. So change the expected test result to __success_unpriv.

3aaa339f64 uapi: in6: restore visibility of most IPv6 socket options
[ Upstream commit 31557b3487 ]

A decade ago commit 6d08acd2d3 ("in6: fix conflict with glibc")
hid the definitions of IPV6 options, because GCC was complaining
about duplicates. The commit did not list the warnings seen, but
trying to recreate them now I think they are (building iproute2):

In file included from ./include/uapi/rdma/rdma_user_cm.h:39,
                 from rdma.h:16,
                 from res.h:9,
                 from res-ctx.c:7:
../include/uapi/linux/in6.h:171:9: warning: ‘IPV6_ADD_MEMBERSHIP’ redefined
  171 | #define IPV6_ADD_MEMBERSHIP     20
      |         ^~~~~~~~~~~~~~~~~~~
In file included from /usr/include/netinet/in.h:37,
                 from rdma.h:13:
/usr/include/bits/in.h:233:10: note: this is the location of the previous definition
  233 | # define IPV6_ADD_MEMBERSHIP    IPV6_JOIN_GROUP
      |          ^~~~~~~~~~~~~~~~~~~
../include/uapi/linux/in6.h:172:9: warning: ‘IPV6_DROP_MEMBERSHIP’ redefined

  234 | # define IPV6_DROP_MEMBERSHIP   IPV6_LEAVE_GROUP
      |          ^~~~~~~~~~~~~~~~~~~~

Compilers don't complain about redefinition if the defines
are identical, but here we have the kernel using the literal
value, and glibc using an indirection (defining to a name
of another define, with the same numerical value).

Problem is, the commit in question hid all the IPV6 socket
options, and glibc has a pretty sparse list. For instance
it lacks Flow Label related options. Willem called this out
in commit 3fb321fde2 ("selftests/net: ipv6 flowlabel"):

  /* uapi/glibc weirdness may leave this undefined */
  #ifndef IPV6_FLOWINFO
  #define IPV6_FLOWINFO 11
  #endif

More interestingly some applications (socat) use
a #ifdef IPV6_FLOWINFO to gate compilation of thier
rudimentary flow label support. (For added confusion
socat misspells it as IPV4_FLOWINFO in some places.)

Hide only the two defines we know glibc has a problem
with. If we discover more warnings we can hide more
but we should avoid covering the entire block of
defines for "IPV6 socket options".

b17fcce707 drm/xe: Make dma-fences compliant with the safe access rules
[ Upstream commit 6bd90e700b ]

Xe can free some of the data pointed to by the dma-fences it exports. Most
notably the timeline name can get freed if userspace closes the associated
submit queue. At the same time the fence could have been exported to a
third party (for example a sync_fence fd) which will then cause an use-
after-free on subsequent access.

To make this safe we need to make the driver compliant with the newly
documented dma-fence rules. Driver has to ensure a RCU grace period
between signalling a fence and freeing any data pointed to by said fence.

For the timeline name we simply make the queue be freed via kfree_rcu and
for the shared lock associated with multiple queues we add a RCU grace
period before freeing the per GT structure holding the lock.

3ea9509cb8 ionic: clean dbpage in de-init

Since the kern_dbpage gets set up in ionic_lif_init() and that
function's error path will clean it if needed, the kern_dbpage
on teardown should be cleaned in ionic_lif_deinit(), not in
ionic_lif_free().  As it is currently we get a double call
to iounmap() on kern_dbpage if the PCI ionic fails setting up
the lif.  One example of this is when firmware isn't responding
to AdminQ requests and ionic's first AdminQ call fails to
